MILK-JAR GAP.

Specification ot Letters Patent. Patented. Aug., 31, i909.

Application llled'September 10, `1908. Serial No. 452,380.

To all whom 'it 'fm1/y comme:

Be it` known that I, WILLIAM B; HAY, of Portland, in the county of Cumberland and State of Maine, and having a post-oflice address 'at,No. 5 West street, 1n said Portland, have invented certain new and useful Improvements in Milk-Jar Caps, of which the-following is a specification.

My invention relates to a cap for milk .jars

as are now in eommonuse for delivering milk. Such caps are commonly made of disks of Waterproof pulp board which are inserted by pressure into the mouth of the jar and are -held in place by an internal shoulder. In removing these caps a hard instrument is often used like a fork or a Screw driver and as a result the glass' is 'often' broken.

The object of my invention is to provide' such a'cap with means by which it can be easily removed withol'xtthe employment of any instrument for this purpose and which shall vat the same time be adapted for rapid manufacture.

The device`consists of a disk .having secured to it 'atene side of the center, a strip of tape, cord,or -,other )like material by a staple which passes thi'ough it between its ends so that the two ends can be used together for pulling, the'ends of the tape be-l ing preferably terminated at the perimeter of the disks.

I illustrate m invention by means of the accompanying rawing in Which- Figure 1 isa plan view of the cap and Fig. 2 is a section showing the staple in elevation.

In the drawing, A is the cap or disk of pulp board and B is the flexible pulling device which is preferably composed of a staple C which embraces the twine an holds it irmly in place. In order to give plenty of bearing for the staple the ends of the latter are turned outward and thence upward buryingr themselves in the body of the pulp and providing a Wide bearing.

The staple is inserted over the cord at some point between the ends so that the ends may be picked up and grasped together to form a handle for pulling up the cap. TheA staple is preferably inserted as here shown in the center of the cord so that the two ends will'be equal length. y 55 The cord is secured to the cap so that it will stand a hard pull without causing the staple to break through, no opening is formed in the ca for the admission of moisture, the edge o the cap is continuous and adapted to form a tight joint with the mouth of the jar and the cap is adapted to be rapidly and cheaply made. y

.as a handle for manipulating the cap. In-

stead of using a piece of twine as shown I may make use-of a tape or any otherlike l. flexible material. v'10\ I elaim:- The herein described milk jar cap, consisting of a {'lat circular disk ot' pulp board, a pulling device secured to the outer face of the disk consisting of an elongated flexible strand of a material differing from that of the disk, and a staple embracing thefpulling device and passing through the material `of the disk, saidstrand extendin at both sides of the staple so that both en portions e0 'may be grasped for ypulling purposes WILLIAM B.
